There was a W. R. Phare who is mentioned on the title of "Visit to Alnwick", see here: https://www.brethrenarchive.org/archive/later-exclusivism/raven-section/glanton-division/visit-to-alnwick/ The address "Heworth, Blackborough Road, Redhill" might help to get more information on him. He is also mentioned as author in the Stow-Hill-edition of "Words of Truth", vol. 1 (1933), p. 116 and in the same magazine, vol. 3 (1935), p. 294. But I am not sure that this is the W. R. P. we are looking for.
